“…Ball milling of powder mixtures of carbonyl iron (99.95%) and electrolytic manganese (99.5%) was carried out in the planetary ball mill AGO-2U for the preparation of binary alloys Fe 100−x Mn x (x=6, 8,10,14,16,18,20,22, 30 at.% Mn). Fifteen grams of material and 150 g of 7.8 mm-diameter steel balls were loaded into hermetic 160-cm 3 steel vials.…”

“…We recently studied the phase compositions of mechanically alloyed Fe-Mn [7,8] and Fe-Ni [9,10] systems in wide composition ranges. We also reported about a significant retardation, compared to the equilibrium alloys, of martensitic transformation in Fe-Ni alloys obtained by ball milling of elemental powder mixtures [11,12].…”

Iron-manganese alloys with Mn concentration of 6-30 at.% were prepared by mechanical alloying. Structure and phase composition of the samples were investigated by X-ray diffraction and Mössbauer spectroscopy. Mechanical alloying results in the formation of b.c.c. and f.c.c. solid solutions with high concentration of structure defects and refined grains. A single b.c.c. phase was observed in Fe-Mn alloys a Mn concentration less than ≤ 8 at.% and, for higher Mn contents, a mixture of b.c.c. and f.c.c. phases was observed. The main features of phase composition of as-prepared alloys consisted in significant widening of single phase concentration range.

“…To overcome the above-mentioned diculties, alternative methods of alloys preparation, such as mechanical alloying, can be used. It is known that mechanical alloying allows one to extend the concentration range of existence of phases [4,5]. This is of particular importance in the case of intermetallic compounds, including quasicrystals.…”

Al73Cu11Cr16 alloys were prepared by mechanical alloying of the irradiated by Ar + ions elemental powders. Evolution of alloy structure at ball milling, as well as during the further annealing, was investigated using X-ray diraction and dierential scanning calorimetry. It was shown that ball milling leads to the Cu dissolution in Al and Cr and to the formation of Al2Cu intermetallic phase. An increase of the milling duration leads to an increase of the Al2Cu phase content in the samples. Ion irradiation of initial elemental powders results in an increase of their interaction rate at milling. In the case of irradiated powders using as initial materials, a content of Al2Cu phase after milling is higher than in the case of using non-irradiated elemental powders. No eect of irradiation of initial elemental powders on the phase transformation at heating was observed. The annealing results in the decomposition of Al-and Cr-based supersaturated solid solutions. An increase in the Al2Cu phase content at heating was observed only in the samples, which were milled for 4 h. In the samples milled for 14 h, nearly no increase in Al2Cu phase content at heating was observed. Heating up to 500600• C results in the single-phase decagonal quasicrystalline phase formation for all of the studied samples.

“…Thus, around the composition of the Permalloy Ni 80 Fe 20 , several excellent soft magnetic properties are observed, like strong susceptibility, a high magnetization and weak losses by hysteresis. These alloys can be obtained by various techniques, such as: cathode sputtering [1], vacuum evaporation [2], "Rapid Quenching" [3], mechanical crushing [4][5][6][7], "Pyrolysis Spray" [8], fusion in cryogenic levitation [9], and techniques in liquid phase such as the electro-deposition. Our case concerns the study of the alloy layers Ni-Fe, with a thickness of approximately 10 µm, which is obtained electrolytically [10,11].…”

This paper will be devoted to the study of the magnetic properties of the layers of Ni 100-x Fe x alloys, obtained by electrolytic deposit. The chemical composition of these alloys varies, according to the content of both constituents nickel and iron, from 50 at% to 90 at% of nickel, for a layer thickness of about 10 µm. We have started a systematic study in order to determine the influence of the atomic composition of nickel on specific magnetization to saturation and the hysteresis loops, as well as the thermomagnetic effects. During our investigations, we noted that, firstly specific magnetization to saturation grows almost linearly with the content of iron of alloy. Secondly, the hysteresis loops present all a low coercitive force and a strong susceptibility. Finally we underlined that the effect of the heat treatment is very strong for the low contents of iron of alloy.
